Friends should already know that the iPhone 13 is in trouble again.
Seriously, to buy an iPhone, you have to have a good mindset. Don't look at the far peak blue I bought the local luxury gold, I can't guarantee that tomorrow we will both be the same color (shai).
The damage of this pink screen is extraordinary, and the first thing to explain is that this time the pink screen does not have a specific display page, but appears randomly.
That is, you use it, eh, directly on the face of pink.
Maybe brushing the album suddenly flashes.
Or just go straight to the face without doing anything, which is much scarier than a haunted house.
In addition, even iPhone 12 and even iPad users have said that they have encountered pink screens.
Just when everyone gathered on Weibo, ready to "denounce" Apple.
Apple customer service is very fast, a snap will come out to declare - everyone do not panic, this pink screen is not a hardware problem, is a software problem Ha ~
The brother felt that this was very familiar, but he did not remember the source for a while.
Go back to Baidu and check, good guys -
It turned out that last year's iPhone 12 green screen door also said so.
At that time, 12 was only released shortly after, some netizens said that they did not even have an object, and the mobile phone was green first.
(Left: Green screen |.) Right: Normal screen)
Although manufacturers can indeed debug the level of green values through the software level. However, the reason for the green screen of the 12 series is a more unified statement is the problem of OLED.
(Left: LCD screen |.) Right: OLED screen)
Because OLED and LCD screens are different, each display unit can control red, blue, and green light. And by controlling the proportions, the colors are revealed.
The problem is that the luminous efficiency of the green itself is higher than that of the red and blue. In the daily brightness and environment, the gap is not large, but in the case of low brightness, this color rendering gap will be widened.
The machine brother found an early WeChat shake screenshot, and it can be seen from the PS color taker that it is not black at all.
If it is pure black, it is fine, after all, OLED can turn off all pixels. And weChat shakes the interface, it is exactly black or not, bright and not bright.
This makes it possible to display pixels, such as invoking the red and blue tricolors to a very low degree.
This also gives the green the opportunity to thrive and directly "dominate" the entire screen to create a green screen.
Of course, there is also a problem with the screen provider LG. However, in the end, Apple launched iOS 14.5, claiming to have fixed the green screen.
At the same time, the WeChat shake interface has also deepened (yes, it is not so gray now), avoiding the embarrassing gray before, and the matter has come to an end.
If you have to talk about the real screen problem of the iPhone, you have to mention the yellow screen.
If I remember correctly, from the era of iPhone 3G, what "cold and warm" screen distinction has already existed.
And it's the kind of phenomenon that the new generation is yellower than the previous generation, or whiter.
In this regard, the machine brother checked the detection of the screen of recent generations of iPhones by a third party.
And with reference to the coloring temperature table, the following figure is obtained:
Brother Ji also taught everyone how to look at this picture by the way: "K" is the color temperature unit, and the lower the value, the yellower the display screen; conversely, the higher the value, the bluer.
After understanding this standard, we can also see that Apple is basically a year of white and yellow jumps repeatedly. On other models, the situation is generally the same.
In addition, the iPhone also has a "True Color Display", which automatically adjusts the coolness and warmth of the screen according to the ambient light. However, in most cases, the yellowness will be deepened, which is naturally "yellow on top of yellow".
Of course, we don't know why Apple always jumps repeatedly.
If it is not deliberate, then it is really necessary to complain about Apple's grasp of quality control.
The most typical quality control problem is this yin and yang screen. This is not to say, this is the flaw screen. I really don't know how to check it when I leave the factory.
And all of this, Apple has never come to admit is its own hardware problems.
Therefore, many netizens have great opinions on Apple's throwing pot to the software this time.
But in fact, this boiling pink screen incident may really be a software problem.
You know, if it's really a screen problem, how can the screenshot still be visible?
Since it is a bug, where does the bug come from? For a while, everyone was confused.
A netizen thought that since the pink screen will be forced to restart, it will definitely have a crash report that begins with "Painc Full" in "Analysis and Improvement".
Although it is a random powder screen, then use the exclusion method -
So he dismantled the iPhone parts one by one, until after removing the tail plug of the iPhone, he reproduced the phenomenon of the netizens' pink screen.
He opens the corresponding crash report. Within a large string of analyses, the words "SMC PANIC" were found.
According to his description, the string corresponds to the air pressure sensor at the tail plug of the iPhone.
That is to say, when the mobile phone detects that the air pressure value is abnormal, and the mobile phone is still in high power consumption operation, it will perform the phenomenon of pink screen restart.
We can also understand that it is an error warning.
Overseas netizens are trying to find problems from the system level. One of the netizens felt that the pink display alarm was likely to be a problem of memory writing errors.
So he feels that there is a loophole in the memory of the mobile phone.
The reason why it is pink, another netizen explained, is because of its special color, the impression of people is very strong, so it is the alarm color in the industry.
We can understand it as like the "blue screen" of a computer.
However, everyone is still speculating, and there is no need to take it too seriously. The official also did not announce the specific problem, let's wait for the follow-up iOS update to fix it.
But the machine brother has a good news: in the latest iOS 15.3 RC version, there is no mention of the fix of the pink screen situation.
Therefore, it is better to buy the iPhone or the next generation.
